Brad Paisley Has Hilarious Congrats to Carrie Underwood on New Baby

Brad Paisley has been good friends with Carrie Underwood for quite some time, and so he predictably was not about to let the birth of his pal's second child go unnoticed on his own social media. The singer took to Instagram to laud the expanded family, slipping in some of his trademark humor.

"Like I said, it’s a Willie! Er...a Jacob!" the singer quipped under a photo of dad Mike Fisher cuddling Jacob Bryan; referring, of course, to the joke he bantered about with Underwood during their dual 2018 Country Music Association Awards hosting duties in November. While throwing out names of famous country couples to rib Underwood. he finally called out "Waylon or Willie," to which Underwood exclaimed "It's a Willie!"

Well, we all understood the double entendre there, and now Underwood is proud mama to two of those. Jacob joins nearly-4-year-old Isaiah Michael Fisher and rounds out the Fisher household to four. The couple had previously indicated a January due date and shared that they were having a second boy, but had not revealed the name.
